paszlib is a Pascal conversion of the standard zlib library: you don't need any external dependencies. It was implemented by Jacques Nomssi Nzali (his old homepage is dead, see a continuation of the project here). It is used in the FCL to implement the TCompressionStream class.

This class lets you compress and decompress .zip files.

The main unit of this package is paszlib. There are other, auxiliary units, but the only unit that needs to be included in a typical program is this one.

TZipper

TZipper은 압축 .zip 파일을 압축 해제에 대한 지원을 하지만 모든 압축 방식을 지원하지 않습니다.

예제

Zip 파일 생성

첫번째 인수에 파일이름을 입력하여 zip 파일을 생성할 수 있습니다. 이후 인자 파일이름을 추가하여 zip파일에 포함합니다.

다음은 생성하는 예입니다.

zipper newzip.zip autoexec.bat config.sys

uses
  Zipper;
var
  OurZipper: TZipper;
  I: Integer;
begin
  OurZipper := TZipper.Create;
  try
    OurZipper.FileName := ParamStr(1);
    for I := 2 to ParamCount do
      OurZipper.Entries.AddFileEntry(ParamStr(I), ParamStr(I));
    OurZipper.ZipAllFiles;
  finally
    OurZipper.Free;
  end;
end.

Zip 압축 풀기

c:\test.zip 압축파일의 모든 파일을 c:\windows\temp\ 디렉토리에 풀기

uses
  Zipper;
var
  UnZipper: TUnZipper;
begin
  UnZipper := TUnZipper.Create;
  try    
    UnZipper.FileName := 'c:\test.zip';
    UnZipper.OutputPath := 'c:\windows\temp';
    UnZipper.Examine;
    UnZipper.UnZipAllFiles;
  finally
    UnZipper.Free;
  end;
end.

스트림 파일 압축 풀기

라자루스 폼위에 TMemo, TButton, TEdit, TFileNameEdit 를 올립니다.

버튼을 클릭하면 FileNameEdit에서 zip 파일을 읽어, Edit박스에 입력된 파일을 압축해제 합니다.

그리고 압축 내용을 Memo에 출력합니다.

uses
  Zipper;

...

procedure TForm1.Button1Click(Sender: TObject);
begin
  ExtractFileFromZip(FileNameEdit1.FileName,Edit1.Text);
end;

procedure TForm1.DoCreateOutZipStream(Sender: TObject; var AStream: TStream;
  AItem: TFullZipFileEntry);
begin
  AStream:=TMemorystream.Create;
end;

procedure TForm1.DoDoneOutZipStream(Sender: TObject; var AStream: TStream;
  AItem: TFullZipFileEntry);
begin
  AStream.Position:=0;
  Memo1.lines.LoadFromStream(Astream);
  Astream.Free;
end;

procedure TForm1.ExtractFileFromZip(ZipName, FileName: string);
var
  ZipFile: TUnZipper;
  sl:TStringList;
begin
  sl:=TStringList.Create;
  sl.Add(FileName);
  ZipFile := TUnZipper.Create;
  try
    ZipFile.FileName := ZipName;
    ZipFile.OnCreateStream := @DoCreateOutZipStream;
    ZipFile.OnDoneStream:=@DoDoneOutZipStream;
    ZipFile.UnZipFiles(sl);
  finally
    ZipFile.Free;
    sl.Free;
  end;
end;
